Justin Bieber performed at the Billboard Music Awards at the MGM Grand Garden Arena on Sunday, May 19, 2013 in Las Vegas. He sang his new hit single, 'Take You,' and returned to the stage a second time later in the show to perform his new song, 'Power,' with will.i.am.
But the most memorable moment for Bieber was when he accepted the Milestone Award. As he walked on stage, he was met with both cheers and boos.
'I'm 19 years old. I think I'm doing a pretty good job and basically, from my heart, I really just want to say it should really be about the music, it should be about the craft, the craft that I'm making. This is not a gimmick. I'm an artist and I should be taken seriously.'
